Resolved: Identifying an array using a string JavaScript

/* This part works in returning the array I need, but it requires that they are placed 
inside an object and returning them based on the key,
which I would want to avoid. */

const obj = { att: [1, 1, 1, 1], btt: [2, 2, 2, 2], ctt: [3, 3, 3, 3], dtt: [4, 4, 4, 4] };
function getOption() {
  let choice = document.getElementById("mySelect").value;
  function pick(name) {
    return obj[String(name)];
  }
  document.getElementById("demo").innerHTML = pick(choice);
// Drop-down choice "att", output "[1,1,1,1]".
}

/* Here, although the arrays are named One and Two and I return a string that is either
"One" or "Two", JS doesn't seem to notice that those are array names
and returns the string themselves. */

const One = ['a','a'];
const Two = ['b','b'];
function getSecondOption() {
  let choice = document.getElementById("mySelectZwei").value;
  function pick(name) {
    return String(name);
  }
  document.getElementById("demoZwei").innerHTML = pick(choice);
// Drop-down choice "One", output "One".
}

var One = ['a','a'];
var Two = ['b','b'];
function getSecondOption() {
  let choice = document.getElementById("mySelectZwei").value;
  function pick(name) {
    return window[name];
  }
  document.getElementById("demoZwei").innerHTML = pick(choice);
}
